Identification of Electro-hydraulic Control System Based on Wavelet Theory

摘要：

A dynamic model identification method of the electro-hydraulic control system based on the wavelet theory is proposed, which is of a higher identification precision compared with the traditional methods. This method makes use of the multi-resolution analysis theory and associates the reconstructed input and output signals with the hydraulic system working frequency band by weighting approach. Simulation results prove that it is more efficient than the least square identification method and provides a powerful base for the controller design of the electro-hydraulic system.
